Post‐Synthetic Modification of ZIF‐8 Crystals and Films through UV Light Photoirradiation: Impact on the Physicochemical Behavior of the MOF

“…ZIF‐8 crystals and films were solvothermally obtained by employing a reaction mixture containing (NO 3 ) 2 Zn.6H 2 O (Zn, Sigma Aldrich), sodium acetate (Ac, Ciccarelli pro‐analysis), 2‐methylimidazole (Mim, Sigma Aldrich) and methanol (Cicarelli pro‐analysis) in a molar ratio of Zn : Ac:Mim:methanol 1 : 2 : 2 : 2000, using a protocol previously optimized . The reactants were stirred for 30 min and then placed in a Teflon‐lined autoclave; the solvothermal treatments were carried out at 120 °C for 10 h. For the ZIF‐8 films, electrolytic copper foils were used as supports which were previously cleaned with water and then with acetone in an ultrasonic bath followed by acid cleaning (5 % w/w HCl, 10 min), washing with distilled water and drying with N 2 .…”

“…In addition, it has a pore size of 11.6 Å which is accessible through windows of 3.4 Å, although its structure is flexible and allows the entry of molecules larger than its openings . Furthermore, the technological applicability of this MOF in many cases requires its conformation as films, whereby ZIF‐8 films have been synthesized on several types of substrates to be used in a broad field of applications …”

“…Zeolitic Imidazolate Frameworks (ZIFs) are a family of Metal‐Organic Frameworks (MOFs) that exhibit good thermal and chemical stability compared to other materials of this class, as well as a high specific surface area . For these reasons, in recent years they have been the subject of numerous studies due to their potential applications in several fields such as gas adsorption, gas separation, heterogeneous catalysis, sensors, microelectronics and drug encapsulation, among others . ZIF‐8 is an archetypal MOF of this family; it has a sodalite topology (SOD), thermal stability up to about 400 °C in an inert atmosphere and good chemical stability in organic solvents, water and alkaline solutions .…”

Exploiting a silver–bismuth hybrid material as heterogeneous noble metal catalyst for decarboxylations and decarboxylative deuterations of carboxylic acids under batch and continuous flow conditions

“…scaleout). [67][68][69] In spite of these obvious benefits, there are very few precedents for heterogeneous silver-catalysts being utilized in continuous flow processes, 70,71 which may be explained by the fact that stable and robust heterogeneous silver catalyst are at scarce. 41,42,72,73 To the best of our knowledge, protodecarboxylations promoted by heterogeneous noble metal catalysts have not yet been achieved under efficient continuous flow conditions.…”
